In OSPF, how does a router ensure that LSAs advertised to a neighboring router are received?
In OSPF, how does a router ensure that LSAs advertised to a neighboring router are received?
In OSPF, when a router sends LSAs (Link State Advertisements) to a neighboring router, the neighbor acknowledges receipt of these LSAs to ensure they were successfully received. This mechanism is in place to provide reliability in the link-state exchange process. Without such acknowledgments, there's no guarantee that the LSAs reached their destination, which would compromise the accuracy and stability of the network's routing information.
Link-state acknowledgment (LSAck)messages provide reliability to the link-state exchange process, by explicitly acknowledging receipt of a Link State Update message. The LSA acknowledgment, explicitly acknowledged, that it have received a LSA, by mirroring it back
